The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

该方法的步骤包括：相机标定：利用泰勒级数模型对全向视觉传感器进行标定，得到相机内参；对极几何关系求取：包括计算双目全向相机之间的本质矩阵，并从中提取相机的旋转和平移分量；外极线校正：对所拍摄的全向立体图像对进行外极线校正，使校正后的极二次曲线与图像扫描线重合；三维重建：对校正后的立体图像对进行特征点匹配，根据匹配结果计算点的三维坐标。

IHT is make used of to proceed line edge fitting in the actual engineering. The auto-adaptable image edge detection method is applied to detect image edge in real project, and the region of image edge detected is limited within 1 pixel. IHT is also applied to fit line edge. Comparing with MHT, the result of IHT indicates its speed quick, the accuracy high, and anti-jamming-quality strong, exactly said that the accuracy of IHT fitted line is less than 0.1 pixel for polar distance and less than 0.01deg for polar angle.
